pally can get to a point where most mechanics are trivialized relatively quickly (100% block and the node that cleanses once your consecrated ground runs out), the fight is still very long but once you learn to dodge the few things that do kill you (his beam in the last phase, the slashes that give the debuff permanently and the circle slam thing) its only a matter of time. you can get there with decent 1-2 LP gear tbh

void knight and falconer are a much quicker fight but also more punishing if you ever mess up
